Last week my MTR system updated to 184.108.40.206. I checked my unit this morning and it seems to have taken an update and is now running 220.127.116.11.
Can't see any release info here https://docs.microsoft.com/en-us/microsoftteams/room-systems/srs2-release-note
We also got version 18.104.22.168 last week which caused SrS not being able to fetch the calendar from Exchange. Today I checked and we now have been updated to 22.214.171.124 and now the error is gone.
So for us it seems like a bugfix :)
